Application filed December 1, 1915. Serial 1%. 64,505.

To'all whom it may concern:

Be it l-KIIOWII that 1, WILLIAM G. MAY- NARD, a citizen of the United States, and a connector. An important objectionto this type of connector is'that it depends on the conductivity of the connector and on the proper connection thereof with the conductor and'with the terminal so that a defective'connection is liable to result either with the onset: the other.

My invention provides a connector in which the electric circuit is established di rectly between the conductor and terminal by directcontact thereof without the intermediary of the connector as a. conducting medium, the arrangement beingsuch that the'sole ofiice of the connector is to clamp the conductor and terminal in direct c0n-,

- tact with each other.

The invention has in view, also, to enable the connection or disconnection of the terminal and conductor to be effected with facility and despatch as well as. tq, insureja good metallic contact therebetween.

The invention will particularly be explained in the specific descriptionfollowing.

Reference is to be had to the accompanying drawings forming part of this specification in which similar reference characters indicate the corresponding parts in all the views.

Figure 1 .is a side elevation of av terminal connector embodying my invention, showing the same applied toabattery terminal and a conductor; Fig. 2 is a' rear perspec- '10 indicates the conductor which may in? volve a single wire or a multiple of wires,

the numeral 11 indicating a threaded terminal secured to a battery element 12 by a nut. 18 as usual.

My improved connector device, designated generally by the numeral 14, includes an element 15 formed with an oblong opening 16, through which the battery terminal 11 is adapted tobe entered axially. The connector is preferably made of sheet metal and the element 15 will, when applied to the battery terminal 11, bedisposed approximately parallel with the battery element 12. The element 15 terminates at one end in. a returned flange 17 preferably curved trans- Yersely to constitutewhat may, in effect, be considered .a broad hook, which is adapted to receive and seat the end of the conductor 10 in a direction transverse to the axis of the terminal 11. The opening 16 extends adjacent to the conductor seat 17 so that, with the conductor 10 lying thereon, it will be adjacent to and may make direct contact with the threaded side of the terminal 11.

The element 15, and a co-acting clamp element 18, are formed respectively'at the opposite ends of a bowed spring presenting an arm 19 integral with the element 15 and extending from that end of said element 15 opposite the conductor seat 17, said arm 19 being return bent to produce the arm 18 and dispose the free end of the latter toward and I adjacent to the element 15 and therefore,

adjacent to the oblong slot 16 through" which the battery terminal is entered. The

free end of the resilient arm 18 is preferably formed with a flange 20 at appi'oximately right angles to said resilient armand lying substantially parallel' ,with the element 15 to present the edge of the flange, laterally to the terminal 1]..

In practice, the resiliency of the clam arms 18, 19 tendsto move the conductor seat I 17 and the flanged end 20 of the arm 18 to- Ward each other, the said lflanged end 20 moving over the opening 16.- Withthe battery terminal 11 and ,the conductor 10 in 'place, the resilient clamp members will thus press the said conductor and terminal against each other in crossed relation, the

clamp elements bearing respectively against. the battery terminal and the conductor, with;

therconductor in direct and firm contact with the threaded side of the terminal.

The opening 16 extends to and partially of said flange is preferably formed with a concave depression 20. By this arrangement the lateral pressure exerted on the terminal" 11 toward the conductor 10will nnfailingly make good contact therewith Without interference from the flange 17 since the terminal is permitted to closely approach he bottom of the said. flange. It is-to be observed that the electric current is established directly between the condiictor and terminal Without being required to pass through the connector device.

Having thus described .my invention 1 claim as new, and desire to secure by Letters Patent: 1 l i 1 A connector of the class described including seat member to receive a conductor Wire, there being an opening in the con nector adjacent to and transversely of the said seat member, forthc entrance axially therethroiigh of a terminal in direction.

transversely of the seat, and a springpressed clamp element having a movementtoward the seat member, across said opening, to engage the terminal and draw the conductor and terminal in direct contact with each other in crossed relation.

2; An, electrical terminal connector having two opposed resilient clamp elements inovable relatively to each other, one of which presents a member adapted to receive a con- 4 v doctor and a terminal disposed in crossed relation between said clamp ele1nen.ts,tl1e said elements acting to press the conductor and terminal in direct contact for thedirect passage of the current Without the interme diary of the connector as a conducting: me dium.

3., In" a de'viceof the class. described, in combination; a conductor, a connector formed with a resilient arm having a mernher on which the said conductor seats and formed with an opening adjacent to said. member, a terminal extending axially through said opening across the conductor and'in. direct contact therewith, and a sec ond resilient arm on said connector hearing against the terminal adjacent to said open-- ing at the opposite side of the terminal from acting to press the mo em conductor and terminal directly against each other. v

i. A terminal connector including an element having an opening extending therethrough adapted to receive a terminal, the said'elcinent being formed at aside thereof adjacent to oneend of said opening with a laterally turned flange constituting a conductor seat, and a resilient clamp element having a free end adjacent to the said opening and movable toand from the said flange across the said opening. 5. A terminal connector comprising a strip of sheet metal bent to forms, bowed spring, one arm of which presents a member formed with an oblong opening therein, the free end of said member being returned in i the form of a flange curved in cross section and constituting a seat for a conductor, said wopening being adapted to receive a terminal transversely of said seat, the other arm of the springbeing disposed in the direction of the member having the opening, the free end of the second arm being adjacent to the said opening and having its terminal bent toward the curved flange.

6 A. terminal connector comprising a strip of sheet metal bent to form a bowed spring, one arm of which presents a member formed with an oblong opening therein, the free end of saidmember being returned in the form. of a flange curved in cross section and constituting a seat for a conductor, said opening being adapted to receive a terminal transversely of said %at, the other arm of the spring being disposed in the direction of the member having the opening, the free end of the second arm being adjacent to the saidopening and having its terminal bent toward the curved flange, saidopening' extending' into the curved flange and the edge of the curved flange having a depression op posite said opening.

In testimony whereof I have signed my name to this. specification in the presence of two subscribing Witnesses.
